A MOVABLE SAFETY GRILLE INCLUDES AN OUTER FRAME(1) HAVING TOP AND BOTTOM RAILS(11), A PLURALITY OF SLIDE ASSEMBLIES(2) MOUNTED IN THE TOP AND BOTTOM RAILS(11), AND A PLURALITY OF PROTECTIVE BARS (3)CONNECTED AT UPPER AND LOWER ENDS TO THE SLIDE ASSEMBLIES(2). EACH SLIDE ASSEMBLY INCLUDES A VERTICAL HOOK (214) AND A CURVED ELONGATE HOOKING STRIP (22) FORWARD EXTENDED FROM THE VERTICAL HOOK (214) TO SUSPEND IN THE AIR. EACH ELONGATE HOOKING STRIP (22) HAS A LONGITUDINAL OPENING (220). WHEN A PRECEDING SLIDE ASSEMBLY IS SLIDE FORWARD, THE VERTICAL HOOK (214) THEREOF MOVES IN AND ALONG THE LONGITUDINAL OPENING (220) OF THE ELONGATE HOOKING STRIP (22) OF A FOLLOWING SLIDE ASSEMBLY TO FINALLY PULL THE LATTER TO SLIDE FORWARD, TOO. WHEN ALL THE SLIDE ASSEMBLIES (2) ARE SEQUENTIALLY PULLED TO EQUALLY SPACE FROM ONE ANOTHER, A SAFETY GRILLE IS FORMED IN THE OUTER FRAME (1). BY PUSHING THE SLIDE ASSEMBLIES (2) IN A REVERSE DIRECTION, THE SAFETY GRILLE MAY BE GRADUALLY FOLDED.FIG. 1
